Star Wars BB-9E

thingiverse

This is a remix of wkarraker's nice BB-8 and uses his BB-8 body design as a foundation for bB-9E's nemesis, BB-9E. This is a work in progress and I will be adding the other pieces as I complete the design and test fit the parts. Printing Instructions: Printed using Monoprice Select Mini V1 - I used a combination of .0875 and .175 layer heights. These are multiples of the "magic numbers" for the stock MP Select Mini. I will note what layer height was used for each piece. I used a top and bottom thickness of 1.2 and sides of 1.2. In general, I used 10% infill and 50mms for travel speed, except as noted. BB-9E_Head_New.stl - Print one copy. I used a combination of Black and Silver PLA. I printed the head at .0875 layer height, 35 mms & 10% infill. I edited the GCODE to add an M600 command at layers 8, 16, 205, 225, 236, and 242. I started using black PLA and when the pauses occurred, alternated between silver and black. If your printer is tuned in well, this will result in a much cleaner line than could be obtained with paint. BB-9E_Head_Eye.stl - Print one copy. I used Black and Silver PLA. I used .0875 layer height, 25mms, and 100% infill. Edit the GCODE to add an M600 command at layer 24. Start with black and switch to silver at the pause. BB-9E_Head_Bottom.stl - Print one copy. I used Black PLA at .0875 layer height, 10% infill, 35mms. BB-9E_Head_Bottom_Ring.stl - Print one copy. I used Silver PLA at .0875 layer height, 10% infill, and 35mms. BB-9E_Head_Blue_Lens.stl - Print one copy. I used translucent blue PLA and printed at .0875 layer height, 100% infill, and 25mms. Edit 1: I've added BB-9E's body ball. There are holes inside the body to accept 8mm x 3mm magnets. I used a dot of super glue to hold the magnets at the bottom of the hole. Make sure you align the magnets in the proper pole orientation to match the other magnets in the body so the head will attach to the body. I used the following magnets for this part of the project: https://www.amazon.com/gp/product/B01MZ6EJE2. Edit 2: I've added the two pieces that make up the bottom of BB-9E's head. The solid ring with the concave section (BB-9E_Head_Bottom.stl) takes one 8mm x 3mm magnet, while the bottom ring (BB-9E_Head_Bottom_Ring.stl) takes two magnets. In the next installment, I will include a wiring diagram. Edit 3: Added the Dome Eye and Blue Lens for BB-9E's head. I used a 3mm white LED with a 120 ohm resistor attached to the positive lead of the LED (long leg). I then attached a length of red wire to the positive leg and used shrink wrap tubing to cover. This assembly will be inserted into the blue lens (BB9E-Blue_Lens.stl). I attached the LED assembly with super glue. I recommend using jpvanderendt's excellent stand design for your completed BB-9E: https://www.thingiverse.com/thing:1718534.
